To all whom t may concern."

Be it known that I, JOHN LURTZ, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Pedestals, of which the followingis a specification. y

This invention relates to a pedestal such as is commonly used in theconstruction of chairs, tables, costumers, and the like, and isparticularly concerned with an improved connection between the pedestalbase and its supporting feet. i a

Anv exempliication of my invention is shown in the accompanying drawingwhere- Figure 1 is a vertical section kthrough the lower end of apedestal to which supporting` feet are attached, one such foot beingshown in perspective in detached relation;

Fig. 2 is a detail in perspective of the lower end of the pedestal base;

Fig. 3 is a perspective view of the clampin member; and Y Iig. 4 is aperspective View of the socket member.

My invention is applicable to pedestalsy of the usual kind employing avertical base adapted to be supported in upright pos1- tion by aplurality of laterally extending feet B which rest upon a Hoor or otherplane support. The particular form and number of such feet is immaterialto my .1nvention, but for convenience inillustration vfour is the numberwhich I have shown. The base is accordingly shown as square in crosssection so as to present one side adjacent each leg. n

Formed in each side of the .base 1 s/a lonofitudinal recess 5 whichextends upward y from its lower end for a desired distance. Each recesspresents in effect a shallow groove of proper dimensions to accommodatea locking plate 6 which is secured to the engaging face 7 of one of thelegs B. By preference each recess decreases gradually in depth at itsupper end, as at 8, until it is ush with the proximate pedestal side,and the upper end of the locking plate 6 Vmay also be bent back as at 9in conformity with this tapered recess end. When the locking plate isfitted within the recess the plate sides lie, by preference, close tothe side walls of the recess so as to `prevent the plate from movinglaterally therein.

n Secured'v to`- theiower end of the pedestal is a socket member C inthe form of a plate whose edges protrude beyondjthe sides of the base. Iprefer that this socket plate should be formed with a square recess 10of proper size to receive the base extremity, thereby adapting one partto be secured immovably to the other as through the use of a screw 11.Extending through the bottom wall of the socket plate are a plurality ofslots` 12, each adapted to receive the lower end 13 of one of thelocking plates 9. Each plate extremity 13 is preferably bent outwardlyto a slight extent, as shown in Fig. 1. With the parts constructed inthis manner, the several legs may be set against the lower end of thepedestal with each locking plate received within a recess 5, the lowerextremity of each plate being thereupon lodged within the proximate slot12 in the socket member. The weight of the pedestal v and its load willtend to hold the upper end of each leg rmly against the base, so that anadequate support for the structure is provided in this manner.

Associated with the upper ends of the several locking plates is a memberD in the form of a clamping ring which is adapted to be moved lengthwiseupon the pedestal base. In operative position it engages with each leg Band the protruding upper end of the locking plate associatedtherewith soas to Y rclamp the same firmly inposition. The several legs arethereupon joined immovably to the base so as to afford a rigidconstruction. Y

It will be noted that the parts comprisingV my invention are few innumber and'may Vbe simply formed. The locking plates may each beattached to the legs as by means of screws, and a similar means ofconnection may also be used for holding Ythe socket member to the base.If desired, the clamping member which ordinarily will stay put throughfriction or otherwise may be locked in position by a screw (not shown).By the means described, it will, therefore, be plain that I haveprovided a pedestal construction which is admirably adapted toVwithstand all the usual conditions encountered in use.
